ISOMETER® isoHR1685DW–925

ISOMETER® isoHR1685DW–925

  • 移动绝缘升降工作平台绝缘监视设备
  • 工作在带电架空线路下的保护
  • 在工作过程中,连续不断地绝缘监视
  • 用于校验绝缘条件的数据存储
  • 随时间变化,绝缘电阻的示意图 (isoGraph)

ISOMETER® isoHR1685DW-925被设计用于在升降作业平台/架空接触网车辆地绝缘监视。设备可以在高达1500V电压的现场运输车辆(尤其是危险车辆)的带电架空线路上工作。为保护操作人员,架空接触网车辆配备了2个绝缘等级。污染、老化或损坏绝缘等级而导致电流对人员危险是可感知的,并显示触电危险。

isoHR1685DW-925对提高这类带电系统工作的安全性做出了宝贵贡献。

安装在车辆中的设备连续不断地监视车辆的绝缘等级。在接近或者正在保养维护期间,当绝缘水平下降到规定的阈值以下时,都将立即通知操作员。可以监视两个绝缘等级。
